DEMOUNTABLE STOP Application filed April 11,, 1929, Serial No. 354,387; Renewed September 11, 1931.

This invention relates to window frames and sash construction and has for its object, a particularly simple and efficient demountable window stop and fastening means therefor, by which the stop can be readily removed for the purpose of removing and replacing thesash.

It further has for its object, a particularly simple and efficient. unitary construction of a window frame and sash, whereby the frame with the sash guide and the sash can be furnished as a unit and the frame readily applied in the window opening of the structure as a railway car, bus or other structure without refitting'the sash to the frame.

The invention consists in the novel features and in the combinationsand constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. V

.Figure 7 This window construction comprises'generally, a frame member, a demountable window stop mounted onthe frame member and means for detachably securing the stop to .the frame member comprising a fastening member carried by the stop and having means for interlocking with the frame member. Preferably, the interlocking is effected by" successive axial and rotative movements of the fastening member and unlocked by the reverse of these movements.

1 designates the frame member which is formed up of sheet metal to have a portion or wall 2 spaced from the wall of the window opening in which the frame is located, it being here shown as a strip formed with an ofiset spaced from the walk of the window opening of the structure to which the'frame is to be applied. The frame member is secured to such structure in any suitable manner as by screws 3.

l designates the sash as a whole, the sash usually having sheet metal frame membersas the hollow stiles 5. The top andbottom' rails are similar to the stiles 5.

6 is the demo-untable outer stop which coacts with an inner stop to form a guide for the sash 4:. The stop 6 is formed up from a sheet metal strip which is angular in cross section, whereby it is open at one side and is arranged with its open side toward the frame member 1. Usually, the stop 6 is in the form of a U shaped channel arranged with the open side toward the offset portion 2 of the frame member. This stop is here illustrated as formed with a curtain guide channel 7 integral therewith, the outer wall 80f which is doubled upon itself and forms a flange which 1govers the front flange 9 of the frame mem- One wall of the channel ofthe stop 6, preferably, the inner wall is formed with tongues (ill 10 at its edges for entering slots 11 in the v i stop 6, the margins of which pieces constitut ing the tongues. The demountable stop 6 is secured in position by fastening members carried by the stop and movable into interlocking engagement with the offset portion 2 of the frame member 1, preferably by a successive axial and rotary movements of the fastening member.

As seen in Figures 1 and 3, the frame member is formed with slots as 12 underlying the window stop 6 and opening into the channel thereof, and each fastening member 13 is formed with a cylindrical body portion 14 movable through a guide hole in the outer or bottom wall of the channel formation of the stop 6 and with an inner stem portion 15 hav ing a lateral or angular extending head or button 16. The button 16 is substantially the same general outline as the slot 12. Upon turning of the fastening member 13 to bring the button 16 in alinement with the slot 12, it can be pushed through the slot 12 and then given a quarter turn to interlock vith the walls of the slot as seen in Figures 1 and The inward movement of the fastening mem ber 13 is against the action of a returning spring 17 carried by the stop member 6 within the channel thereof, and it is here shown as a spring leaf secured at one end to the bottom wall of the channel formation of the stop 6 and having its other end formed with a passage through which the stem portion 15 of the fastening member 13 extends, the

spring 17 being tensioned to pull outwardly on the fastening member 13 and the spring shouldering against the head of the fasten ing member. Any number of these fastening members may be employed. The head of the fastening member 13 is formed with a screw driven slot 18.

To remove the sash, the member 13 is given a quarter turn to bring the button 16 in line with the slot 12, whereupon the spring 17 reacts to move the fastening member 13 outwardly axially moving the button 16 through the slot so that the stop member 6 can be re moved and hence, the sash 5rem'oved. Upon replacement of the sash, the window stop 6 is replaced with the reverse of these opera tions, the tongues 10 being fitted in the locating slots 11. The fastening member is then turned, if it is not already turned, so that the button 16 is alined with the slot 12 and then pushed inwardly to carry the button 16 through theslot and then, the fastening member 13 given a quarter turn to interlock the 'button under the offset portion 2 of the plate 1. By reason of the tongues 10 and slots 11, the stop is quickly and accurately located so that the fastening member 13 registers with v the slots 12.

In the window construction here shown, a double sash is shown with an intermediate stop 20 which forms the inner stop for both of the sashes 5 and the inner stop is provide-d with compression means for forcing the 'sashes 5, 5 against their stops 6.

In the double sash construction Figure 2, the frame member 1 is also formed double or with two offset portions 2 and the inner stop 20 is formed up of sheet metal in the form of a channel with its open side set into the depression at 21 between the two offset portions 2.

The compression devices are shown as plungers 23 extending through guide holes in the sides of the hollow stop 20 with the compression springs 24 between them, these plungers thrusting against strips 25 which bear on the inner sides of the stiles 5 of the sashes 4. 7

As seen in Figures 6, 7 and 8, the compression devices comprise generally, strips 26 on opposite sides of theinner stop 27, these being pressed outwardly against the stiles of the sash by bow springs 28 pressing at their ends against the inner stop 27 and intermediate of their ends against the inner sides of the strips 26. The strips 26 are guided in their compressing movement by stems 29 extending through the central part of the springs 22 and secured at their ends at 30 to the strips, the stems sliding through guide openings 31 and 32 in the side walls of the channel formation of the inner stop 27. The compression features form no part of this invention but are reserved for divisional application.

Each lower sash is usually provided with a sash holder 33 at each corner, this including a movable locking member or bolt 34 which is operated in any suitable manner by a lever 35 located in juxtaposition to a pinch handle 36 on the casing of the sash holder 33. The bolt is located in the hollow lower rail 37 and one of the stiles 5 of the sash and projects beyond the edge of the sash through a suitable opening therein into any one of a number of slots 38 formed in the offset portion 2 of the frame member 1. These slots 38 are formed by slitting and indenting a portion of the plate 1 as shown at 39.

Owing to the removal stop and the means for securing it in position, the stop can be quickly and readily removed and replaced and hence, the sash readily removed and replaced for any purpose whatsoever.

Owing to the frame member 1, the sash and frame can be built as a unit one to fit the other and the frame member 1 mounted in the window opening of a vehicle body or building without requiring refitting of the sash.
